MACHINI. FOR PUNCHING AND REENFOR-CING BLANKS.

Application filed February 5, 1923. Serial No. 617,181.

In the manufacture of shipping tags, shipping envelopes, and various other articles, which. are designed to be supported or fastened by a string or wire passing through an opening in the article it is necessary to'punch such an opening i. the article, and also to reenforce the margins of the opening to prevent the'same from tearing out.

My present invention aims to provide a machine for automatically punching and recuforcing the openings-in articles of this character. \Vhile a shipping envelope is shown in the present instance, particularly in Fig. 13, as the article" operated upon by the machine, it should be understood that many articles of paper or cardboard, such,

for instance, as shipping tags, calendar backs, and many others, are capable of being operated upon by the machine, and such articles are hereinafter to be comprehended within the term blanks which will be used herein in its generic sense. j

One of the primary objects of my present invention is to provide a machine of the 5 character indicated which willautomaticaliy handle the blanks, the reenforcing material, and the eyelets, if they be used, and one which will be extremely speedy and reliable in operation as well as ,entirely automatic, so as to relieve the operator of any manual manipulations except keeping the machine supplied with material and removing the completed product of the machine.

With these general aims in View, my invention contemplates a machine which will automatically remove blanks, one at a time, from a magazine and feed them in succession to an operating station, where they are (li.-.-1 )osed between two strips of reenforcing material, and at which station reenforcing disks are cut from the material, applied to opposite faces ofthe blank, and punched so as to form an opening or eye extending through the blank and through the reenfore-' ing disks on each face thereof, thus providing an opening which is marginally reenforced on both faces of the blank. The blanks arethen moved to another station, where, if desirable, metal eyelets are autoopening and riveted or clinched at each side, thus providing further reenforcement for the opening. From the eyelet station the envelopes are delivered in succession to a delii'ery magazine in which they are packed matically inserted through the reenforced' and from which they may be removed in quantities by the operator and boxed for shipment.

For the purpose of facilitating an understanding of my invention, I have illustrated on the accompanying drawings a preferred embodiment thereof, but it should be manifest that the scope of the invention is not circumscribed by the structural details shown, but on the contar the invention may be embodied in machines differing widely in structure.

Power is applied to the ma- I chine through a belt pulley 17, loosely mounted upon the main drive shaft- 18 and adapted Handling the blanks.

Referring more particularly to Figs. 1, 6,

l and 7, it will be seen that the blanks designated by reference character 22, and which,

as previously stated, may be envelopes, cards, tags, or other articles are stacked on ed e in an inclined magazine 23 near the top 0 the machine, the foremost envelo es being held in position in the magazine y a )lurality of upper retaining fin ers 24, and ower retaining fingers 20, which engage the u per and lower edges, respectively of the oremost blank.

The blanks are pulled forwardly, one at a time, from the magazine by pneumatic transfercrs'or suction cups 25, carried upon a forked pipe 26 to which suction is supplied through a pipe 27 from 'a suction pump 28. This pump, of the reciprocator type, is operated through an eccentric 29 f rom a cam 31mounted on the main drive shaft 18. The suction cups are moved toward and from the magazine by a bell crank lever 32 fulcrumed in a bracket 33 and oscillated by a link 34, connected at its lower end, as shown in Figs. 1 1 and 4, with a lever 35 carrying a cam follower 36, which is held against the perimeter of a cam 37 on the shaft 18 by a tractile spring 38. The foremost blank in the .magazine iswithdrawn therefrom u on retraction of the suction cups engage therewith and disposed in operative relation to 40 a feeding or transferring mechanism, which will now be described. This feeding mechanism comprises a pair of endless chams 39 trained over upper and lower sprockets 41 and 42, respectively, and also around an adjustable tightening idler 40 mounted in a bracket 43, which is adjustable by means of an adjusting screw 44 and a clamping bolt 45 upon the ledge 46 of the machine frame. Pins or studs 47 extend outwardly from the faces of these chains in position to engage the upper edge of blanks disposed against the face of the chains by'the pneumatic suckers as previously described, and whereby the blanks are fed downwardly at each actuation of the feed mechanism. Springs 48 and 49 yieldingly urge the blanks against the chain beneath the magazine and against a plate 51 extending between and at either side of the feed chains. and slotted to accommodate the chains so that the faces thereof lie substantially flush with the face of this plate. The chains are actuated intermittently to impart a step-by-step movement to the blanks by mechanism best illustrated in Figs. 1, 2, 9, and 10. The sprockets 42 are fixedly mounted upona shaft 52, which'adjacent one side of the machine has fixed thereon a gear 53, meshing with and adapted to be driven by a gear 54, loosely mounted upon a stub shaft 55 and provided with a ratchet wheel 56. -A lever 57,'the hub of which is fulcrumed upon the shaft 55, is grovided at one end with a pawl 58 adapte to engage the ratchet, wheel 56 and impart'a partial revolution thereto at each oscillation of the lever. A link 59, connected with a strap 61 surrounding an eccentric on the main shaft 18, imparts an oscillatory movement to the lever 57 to thereby move the blank feeding chains a predetermined distance at each actuation. In order to prevent over-feeding of the chains, the shaft 52 i has fixed thereon a brake drum 62 (Fig. 10) covered with brake lining 63, made of any suitable material, and surrounded by a brake member 64, the tension of which ma be regulated by an adjustable bolt65. his constant braking action not only prevents overfeeding or overthrow of the feed mechanism,

but also holds the feed chains in proper position during the operations upon the blanks supported thereby.

At one or more stations at which the blanks are stopped under control of the feed chains, certain operations are performed thereon, which will be later described, and

when these stations have been passed by the blanks it becomes necessary to impart a horizontal movement to the. blanks in the direction oftheir major axes to free them from alignment with the gumnied waste strips of reenforcing material at that time disposed in roximity to each face of the blank, as will e later ex lained.- The mechanism for imarting this longitudinal movement to the lanks is best shown in Figs. 6 and 12, re ferrin to which, it will be observed that the right-hand edge of each blank, as it aproaches the limit of its feeding movement y the feed chains, enters a groove tififlarried by a horizontally reciprocatory pusher 67 hifurcated to straddle the shaft 18, as shown in Fig. 6, and equip )Cd with a cam follower 68, held by a tractiie spring 69 against the perimeter of a cam 71 on the shaft 18, by which reci n'ocatory movements are imparted to the pusher. By means of this pusher each blank is pushed horizontally into a delivery or stacking magazine 72 at the back of the machine. In this magazine the blanks are packed against a yieldingly retreating block or plate '73 (Fig. 7) by means of a reciprocatory packer 74 carried by a rod 75 projectinghorizontally from an upstanding portion 76 of a reciprocatorv slide 7 7 provided on its lower surface with rack teeth 78. A toothed sector 79, fulcrumed at 81 upon the machine frame, as shown in Fig. 2, is oscillated through a link 82 by an eccentric strap 8;) embracing an eccentric 84 upon the shaft 18,

' to thereby reciprocate the packer in timed one end to the knife and at its other end to relation with respect to the actuations of the feed chains and the horizontal pusher to thereby pack theblanks in vertical position in the magazine 72. Each blank is retained in position in this magazine upon retraction of the packer'by one or more pawls or fingers 85 engaging the upper margin of the blank. Handling the ween orcing material.

The reenforcing material fromwhich the reenforcing disks are produced is of ribbon 0r tape-like structure, and is wound upon two spools 86 which are supported upon arms '87 projecting laterally from the machine, as shown in Fig. 1. Thls reenforcingmaterial, indicated by reference character 88, is un- Wound from the spools, carried beneath de- 2'0 pressing guides 89 and 91, and over a roller 92 partially submerged in liquid in a container 93. The reenforcing material mayeither be previously gummed with suitable adhesive on its inner face, in which event the rolls 92 are simply moistening rolls to 'render the gum adhesive; or the material may be ungummed, in which event the adhesive is applied by the rolls 92. In either event, when the tape leaves the guides 91, :10 the adhesive face is disposed downwardly.

To reverse this face so that it will be opposed to the blanks for adhesion thereto, a half twist is imparted to the tape, as indicated at 94 in Fig. 2, between the guide 91 and the guide pulley 95 from which the tape is trained. From the pulleys 95, the tape extends downwardly in alignment with and in proximity to the oppositefaces of the blank and continues downwardly through guide slots 96 (Fig. 8), the edge of the blank being guided in the meantime in a central guide slot 97. At apoint beneath the horizontal blank pusher 67, by which the blank is pushed from between the tapes, these tapgs pass between corrugated feeding rollers 98 and 99 (Figs. 1 and 11), the rollers 99 being adjustable toward and from rollers 98 by adjusting screws 101. For purposes of manually reeding the tape, for adjustment or other reasons, the shaft 102 upon which rollers 98 are mounted, is provided with a handwheel 103, as shown "in Fig. 11.. These feed rolls are intermittently actuated in timed relation with the movements of the feed chains by mechanism which will later be described, and after passing through these rolls, the tape, the two strips of which are then stuck together. is deflected horizontally along a tray 104 at the outer end of which there is pivotally mounted at 105 (Figs. 1, 4, and 6) a knife 107, which cuts the tape into lengths so that long pieces of tape will not curl up and become tangled with the feet of the operator and dragged around the floor. A lever 108 is pivotally connected at the machine frame, and this lever is verti cally actuated to operate the knife by means of a link 109 connected'with an eccentric .strap 111 surrounding an eccentric 112 upon the shaft 18, just inside the fly wheel 113 mounted upon the outer end of this shaft. The two strips of tape are therefore unrolled from their respective spools, gummed or moistened, as the case may be, fed down wardly with their gummed faces opposed and in roximity to the blank to be reenforced, tie disks are-cut therefrom and applied to the blank by mechanism which will be later described, the feeding movements are imparted to the tapes intermittently in timed relation with the movements of the blank, and the tape scrap, after the reenforc-' ing disks have been formed, is delivered at the bottom of the machine and cut into relatively short ends.

Applying the reenforcements.

Referring now to Figs. 7 and 8, it will be observed that when a blank is positioned by the feeding chains in the slot 97 between the tapes disposed in the slots 96, the blank .and tapes are all disposed between horizontally movable op osed punches 114 and 115, respectively. unch 114 is fixedly mounted in a slidable rack 116, the teeth of which are in mesh with an oscillatory drive pinion 117 fixed on a shaft 118, to which an arm 119 is connected. Punch 115 is yieldingl mounted in a rack 121 adapted to be reciprocated by a pinion 122, mounted on a shaft 123, similarly equipped with an operating arm 124 (Fig. 2). The two arms 119 and 124 are actuated in unison bylinks 125 connected with eccentric straps 126 sur-' rounding eccentrics 127 on the main shaft 18to thereby reciprocate the punches 114 and 115 simultaneously, but in opposite directions, thereby forcing the punches through the aligned eyes 128 (Fig. 8). The conjoint action of each punch with its eye, in which it snugly fits, punches a disk from each tape of reenforcing material and applies the disks thus punched out, under considerable pressure, to the oppo1ed faces of the blank disposed in the guide slot 97 between the punches These reenforcing disks are therefore firmly applied to opposite faces of the blank to which they are affixed by the adhesive on the disks.

It will be observed from Fig. 8 that the punch 115 carries a smaller centrally disposed punch 129 projecting a limited distance beyond the end of punch 115. The rear end of the rod forming the punch 129 adjustably disposed in a split clamping sleeve 131 and may be adjusted longitudinally toprojcct any desired distance beyond the face of punch 115 by simply loosening the sleeve 131. Punch 115 is yieldingly held in projected position by a coiled expansion spring 132 disposed within the rack 121, the tension of this spring being regulated by an adjustable collar 133 thgeaded into the outer end of the rack. lhe other punch 114 and its rack 116 are provided with a central bore 134 adapted to receive the projecting end of unch 129 so that when the punches 11 1 and 115 are'forced together to cut out and ap ly the reenforcing disks, the punch 129 is orced through bothof the applied disks and through the interposed blank, thereby forming a central opening or aperture extending entirely through the blanks and the reenforcing disks. The small waste pieces punched from the disks and the blanks by the punch,129 are forced through the bore 134 by succeeding pieces, and finally are discharged ,from the bore into a chute or rece tacle 135 (Fig. 7).

or some classes of work the reenforcement of the punched opening in the blank b the surrounding reent'orcing disks is sullicient, and in that event the blanks arc sinipl y fed on through the machine, and without further operation thereon are acked in the magazine 72. Some classes 0 work, however, require further reenforcement of the opening by a metal eyelet, and the mechanlsm by which such reenforcing eyelets may be applied will now be described.

Referring again to Fi 7 and 8, it will be observed that beneati the punches 114 and 115 a distance equal to the travel of a blank at each actuation of the feed chains there is mounted another pair of punch carrying racks, indicated by reference characters 136 and 137, respectively. Each rack is actuated from a pinion 1.38 mounted on a shaft 139, which is )rovided with an arm 1.41 connected by an adjustable link 142 with an arm 143 fixed on' the respective shafts 118 and 123, so that at each actuation of these shafts to operate punches 111 and 115, a similar and simultaneous movement will be imparted to the punch carrying racks 1236 and 137. Rack 136 carries an adjustable punch or anvil member 141, and rack 137 carries a similar anvil member 145, in which is disposed a pin 146 yieldingly projected into the position shown in Fig. 8 by a coiled expansion spring 147. This pin is adapted to remove an eyelet from a magazine, which will be later described, and align such eyelet with the opening in the blank previously produced by the punch 12$), whereupon movement of the anvil members 141 and 115 toward each other will insert the eyelet through the opening and upset or rivet the ends thereof on the outer faces of the reenforcing disks, thus anchoring the eyelet in the opening. The eyelets, indicated by reference character 148. are disposed in a magazine 119 (Fig. 7) from which they are fed in succession into a chute 151, extending plying a metal eyelet thereto.

laterally and downwardly substantially into alignment with the end of pin 1 16 when the punch rack 137 is in retracted position. The eyelets may be fed automatically from the magazine into the chute, or a quantity may be intermittently fed into the chute by manual manipulation of a crank 152, which actuates mechanism causing the delivery of the eyelets into the chute. The magazine and chute are pivotally mounted at 153 upon a standard 151, and the chute is normally tilted downwardly into substantial ali nment with the pin 146 by a spring 150. he delivery endot' the chute 151 is so constructed as to hold an eyelet in position to receive the pin 146 upon movement of the same t9 the left, viewing Figs. 7 and 8. When an eyelet has therefore been removed from the chute and positioned on the pin, as shown in Figs. 7 and 8, it is desirable that the chute be elevated out of the path of rack 137. To accomplish this result, the chute is supported upon a roller 155 disposed in the path of travel of a cam 156 positioned on the top of rack 137, near the inner end thereof. \Vhen, therefore, the rack is moved to the left, viewing Figs. 7 and 8, this cam will engage the roller 155, thereby causing the end of chute 151 to be tilted upwardly clear of the rack. When the rack is retracted, the chute will auto matically lower to dispose the next eyelet in the chute in position to be removed therefrom by the pin 146 upon the next actuation of the rack.

In Figs. 13 and 11 I have illustrated a shipping envelope which has been provided with a reenforced opening in accordance with my invention. Referring to these figures, it will be observed that the reenforeing disks or patches 157 have been applied to 0p posite faces of the envelope, a hole has been punched by the punch .129 through the envelope and reenforcing patches, and this opening has been further reenforced by the introduction of a metal eyelet 148 therein, the ends of which have been upset or riveted over, as will be apparent from Fig. 14, by the action of the anvils 144 and 145.

It will be apparent, therefore, that the machine of my invention is adapted to automatically cut and apply reenforcing disks or patches around an opening punched in a blank, and will also further reenforce such opening, when desired, by automatically a p The reenforced opening is adapted to receive a string, wire, or other means of attachment of the blank to an article to be shipped, so that there is no danger of the string or wire becomine torn from the blank. Should it be desira le to reenforce the opening by the disks or patches only, the eyelet applying mechanism may be rendered inoperative by simply tilting the eyelet delivery chute into inoperative'posit-ion and fastening it in that position so no eyelets will be delivered to the pin 146; The eyelet applying anvils Automatic tape and eyelet feed control.

The mechanism for actuating the tape feeding rolls 98 is designed to be automatically thrown out of operationin the event of failure of envelopes to be fed through the machine; otherwise, unless the machine were stopped, the tape' would continue to feed, disks would be punched therefrom, and

' these disks would not only tend to clog the machine, but considerable waste of tape might result. The tape feeding mechanism and the-automatic control therefor will now be described.

Upon the tape feed roll shaft 102, best shown in Figs. 2, 5, and 11, there is mounted a ratchet wheel 158, which is intermittently actuated by a reciprocatory pawl 159 pivotally suspended froma lever 161, carrying a follower 162, which is retained in engagement by a tractile spring 163 with the perimeter of a cam 164 on the shaft 18. This pawl 159 may be swung from the operative position shown in full lines in Figs. 5 and 11, to the inoperative position indicated in dotted lines in said figures, by a bell crank lever 165 fulcrumed at 166 upon the machine frame, and connected by link 167 with a lever 168 (Figs. 1 and 7) pivoted in a bracket 169 and carrying a curved finger 171, which is normally urged toward the plate 51 along which the blanks travel. The end of lever 168, to which link 167 is connected, is suitably weighted so that the finger 171 will be normally urged toward the left,

viewing Fig. 6, under the influence of gravity. The plate 51 is provided with a slot 172 adapted to receive this finger when no blank is interposed between the finger and the plate; consequently, in the absence of a blank, the lever 168 will rock in aclockwise direction, viewing Fig. 6, the finger 171 in this event passing intothe slot in the plate 51, and this rocking movement through the intermediary of the link 167 will rock the bell crank lever 165 in a counter-clockwise direction, viewing Fig. 5, thereby through the sliding sleeve173 connected to the bell crank and slidably surrounding the pawl 159, swinging said pawl out of operative position with respect to the ratchet 158 into the dotted line position shown in Figs. 5 and 11. The pawl will therefore reciprocate idly until the feeding of the blanks is again started, whereu on a blank traveling along the plate 51 unc er the influence of the fee chains will engage the finger 171 and cause it: to be withdrawn from the slot 172, thereby rcstoring the pawl 159 to operative position, so that the feeding of the tape will again be inaugurated.

In order to likewise render the eyelet applying mechanism inoperative upon failure of the feeding of the blanks, there is adjustably mounted upon the link 167 a roller 180 (Fig. 7 which, upon downward movement of the link, as previously described, engages the magazine 149, tilting the same downwardly to thereby'elevate the lower end of the chute 151 so that no eyelets will be positioned in the path of pin 146, and this pin and the anvils will therefore operate idly without wastage of eyelets.

It is believed that the construction, op-

oration, and many of the inherent advan-,
